I've been noticing this for a few days now: audio content (the podcasts, premium or otherwise, Interview Dumptruck, Gaming Minute) doesn't work. The web player and download links point to nothing.
From my limited technical understanding, they're simply not on v.giantbomb.com? The 8-4 Play podcast works because that is hosted on libsyn.
And after some more sleuthing on my part: download links on video don't work either. Seems to be a problem with v.giantbomb.com in general.
EDIT: Oh, completely forgot to mention, tested this on both Chrome and IE11, Windows 7.
